Reddit vs X (formerly Twitter)

Steve Huffman and Alexis Ohanian applied to Y Combinator in 2005 with an idea for a mobile food ordering app called "My Mobile Menu." Paul Graham rejected it. He then called them back and told them they should build "the front page of the internet" — a social news aggregation site where users voted on links. Huffman and Ohanian built Reddit in three weeks. It launched in June 2005. The concept was simple: users submitted links, other users voted them up or down, and the most popular content rose to the top.

Conde Nast Publications acquired Reddit in October 2006 for a reported $10-20 million — less than 18 months after its founding. Conde Nast gave Reddit relative autonomy but limited resources. Reddit was spun out as an independent subsidiary in 2011, eventually becoming a standalone company with Advance Publications as its primary shareholder. It would take another 18 years to reach the public markets.

In January 2021, users of the r/WallStreetBets subreddit coordinated to buy shares and call options in GameStop — a struggling video game retailer heavily shorted by hedge funds. The buying pressure drove GameStop's stock from approximately $20 to a peak of $483 in two weeks, causing billions of dollars in losses for short sellers including Melvin Capital, which required a $2.75 billion bailout. The episode demonstrated that online communities could move financial markets in ways that regulators and institutions had not anticipated.

Reddit announced in 2023 that it would charge third-party developers for API access — fees so high that most third-party Reddit apps became unviable. Thousands of subreddits went dark in protest. Reddit held firm. The API restructuring had a secondary benefit: it positioned Reddit to monetise its archive of 18 years of human conversation for AI training. Reddit signed a $203 million data licensing deal in January 2024 — including a $60 million per year agreement with Google and approximately $70 million per year with OpenAI, giving both companies access to Reddit's real-time content for AI model training.

Reddit went public in March 2024 at $34 per share — a valuation of approximately $6.4 billion. The company reported $1.3 billion in revenue for 2024 — up 62% — though still with a net loss due to IPO-related costs. In 2025, Reddit achieved full-year GAAP profitability for the first time in its history, posting $530 million in net income on $2.2 billion in revenue — up 69%. The company that Paul Graham had told two founders to build, sold to Conde Nast for under $20 million, and had survived 19 years without profitability, had become one of the most successful internet businesses of the AI era by owning the one thing AI companies desperately needed: authentic human conversation at scale.

The idea for Twitter came from Jack Dorsey during a brainstorming session at podcasting startup Odeo in March 2006. The first tweet was sent by Dorsey on March 21, 2006: "just setting up my twttr." The name Twitter was chosen because it described the short bursts of inconsequential information that birds make. Within four years, Twitter had become the nervous system of breaking news worldwide.

Jack Dorsey was removed as CEO of Twitter in October 2008 by co-founder Evan Williams, who took over the role himself. The official reason was that Dorsey spent too much time on personal interests — including fashion design and yoga. Dorsey went on to found Square (later Block). Williams later said firing Dorsey was simultaneously the right decision and the wrong decision.

Elon Musk began buying Twitter shares in January 2022, eventually accumulating a 9.1% stake. He offered to buy the entire company for $54.20 per share — $44 billion total. Then tried to back out. Twitter sued him. A Delaware court ruled against Musk. On October 27, 2022, Musk completed the acquisition, walked into Twitter headquarters carrying a sink, fired approximately half the company within 48 hours, renamed it X, and replaced the iconic bird logo with a stylised X. Brand consultancies estimated the rebrand destroyed $4 billion in brand value overnight.

Musk renamed Twitter to X in July 2023, describing his vision as a WeChat-style "everything app" combining payments, messaging, news, and social media. Advertisers fled over content moderation concerns. Revenue fell by an estimated 50% from Twitter's pre-acquisition levels. Musk responded by suing advertisers for what he called an illegal boycott. Linda Yaccarino, hired as CEO to rebuild advertiser relationships, resigned in July 2025.

In March 2025, Elon Musk's AI startup xAI formally acquired X in an all-stock deal that valued X at $33 billion — $11 billion less than Musk had paid for it three years earlier. xAI, which had been valued at $80 billion, absorbed X to combine its Grok chatbot with X's 600 million monthly users and real-time data. The combined entity, called xAI Holdings, was worth approximately $113 billion. Musk had effectively bought Twitter from himself — using a company he had founded specifically to compete with OpenAI.
